How do I change a Windows desktop icon that won't change?

If you can see this, it is a portion of my Windows desktop (post-support Win10 Professional) where the LibreOffice icon is the conventional sheet-of-paper icon used for documents by Windows. I still can not change it to the official icon despite having administrator privileges on this system due to being its only user. Please help me change this back to what it’s supposed to be.

That… did not work. Obviously this is a Windows issue, maybe app compatibility. I will investigate further along that line.

Not compatibility, it shows the correct icon in my Windows 10 laptop. Do you see the same icon in the soffice.exe file as shown below? The screenshot is of Properties of my desktop icon which is a shortcut to LibreOffice.
